I would like to upgrade my exisiting enviroment  of two call managers sub and primary 4.x and one unity box 4.x to the latest version.


Options and questions are:


Upgrade old hardware to support upgrade.  _ not likely

Purchase cisco boxes   - not prefered

purchase dell servers and install upgrades on and migrate enviroment

VM some of the solution ,,,,


Whats the best versio to move to   is 8.x stable at this point... or should we go to 7.x   is there a good document or video on this migration since it changes alot and changes lic's ...
